While the screw 4'7 is p re- Vlocked in position fornormal use and may be erably a wing screw, it may be a slotted` head* unlocked' to allow. raising ofthe pivot when screw, Lhead screw or other type if. desired." the seat back is tobe turnedto position for Opposite the wing screw 7, the. n ier'nber. 5` is 75"' use as a bed. provided with a vertical slot 8 and a pivot pin l These objects 'and the several novel features 9 isinserted throughtheaperture"providedin of the invention are hereinafter more fully defthe' end 4` of the yframe v3 and extendsintol the scribed andclaimed and the preferred form of slot` 8, of the Vmember 5. This pivotpin is proconstruction by which these objects 'are atvided'with' a yhead'and the head is 'formed 'to 30` tained is shown in the accompanying drawing providea recess to receive the end of the wing in whichg screw 7. Inthis position the member 3 may i' Fig. 1 is a side elevation showing the relative be turned on the pivot pin 9 lfor normal use position of the front and rear seats. and it will be noted that the corner post 1' is Fig. 2 is an enlarged section taken on line provided with a shoulder 10 against whichthe v135 A-A of Fig. 1 with the parts broken away at ange ofthe member 3 vmay engagetosupport the pivot to show the construction. the seat back in the upright position shown in Fig. 3 is a section taken on line B-B of Fig. 2. Fig. 1. Bodies of the coach type are usually equipped As will be understood from-Fig; 3,'the member with seats in which the back of the front seat 5 is cutaway at theA front tov allow the seat 4back i90 'Y i may be folded forward and the folded seat may to be turned forward over the cushion 11 shown then be tipped forward toV allow access to the in Fig. 1; In order toturn the seat backdownrear seat of the coach body. My invention seeks wardly to the position shown in dotted lines in to provide a hinge which will allow this normal Fig. 1, theV wing screw 'I is unthreaded from the 40 operation of the front seat and which hasthe "recess in the pivot pin 9 which allows the seat`f95 additional advantage that the back of the seat back to vbe raised to the 'dotted position shown may be raised and turned backwardly to horiin Fig. 1, and this movement `is limited by the zontal position to provide, in combination with pivot pin 9 engaging against the upper endofthe the front and rear seat cushions, a continuous slot 8. When raised to this position', the flange cushion surface which may be utilized as a bed. of the `back frame 3 will clear vthe shoulder 10 lDv In coach seats of this type, the base ofthe vof the member 1 and allow the seat back to bev seat is usually provided with a pair ofupward turnedv to the dotted position shown in Fig. `1' l ly extending corner posts l which are each' pro- In this position, the frame 3 engages against the i vided with a pivot aperture2 therethrough as shoulder 12 provided 'on the memberv 5 and will shown in Fig. 2. The seat back is usually thus support the seat-back in the dotted posi- T05' i Y formed from a strip of angle iron 3 which is tion shown in Figs. 1 and 3. When it is again bent to inverted U form of substantially the desired-to use .the seat back in the normal manshape of the seat back and this frame 3 is proner, the back 3is turned ,to the yupright position vided with an extending end 4`.having an aperand is pushed downwardly to bringthepivot pin 5 55 ture therethrough so that a rivet may be in- 9 to alignment .with the wingscrew 'I at which 110 time, the wing vscrew 7 may be turned up to engage the recess in the pivot pin 9 and thus lock the pivot in position for normal use. It is to be noted that the side 13 of the corner post 1 allows clearance for the head of the pivot pin 9 and ythe standard coach seat and to preventtearing of the clothing the wing screws '7 are positioned out of the way on'the inner sides' of the seat back frame 3. On original installations the member 5 may be formed as an integral part vof the member l or may be weldedv thereto, if desired. Y'

From the foregoing description it becomes evident'that the deviceis very simple and eiiicient in operation, will not' easily get out of order, pro videsl ra means for locking the movable seat pivot in the normal position and provides a device which accomplishes the objects described.

Having thus fully'describedvmy invention, its utility and mode of operation, what I claim and desire to secure by Letters o1" the United States is Y l. In a hinge yfor automobile seatsv including a seat cushion provided with a pair of corner posts each having an aperture and a shoulder at the uppery end, a tubular member adapted to be secured over each corner post,r a wing screw .threaded through `each tubular member Vand adapted to extend through the aperture in the upper end ofthe respective corner post, a seat back vframe, a pivot pin carried thereby, the Vtubular member being provided with a slot in which the pivot pin is adapted to ride, the pivot pin being provided with a recess to receive the wing screw when in position `atthe lower yend of lbeing arranged tozclear the stop when the I the slot and the seat back frame being adapted to engage the shoulder of the corner post when the pivot pin is in thelower end of the said slot, the arrangement being such that upon release of the wing screw the seatfback frame Aand pivot pins may be raised toY allow the frame to clear the shoulders of the corner posts and a shoulder on each tubular member adapted to support the seat back frame in substantially horizontal position.

2. A hinge for 'automobile seats comprising a tubular member ladapted to be secured over the cornerpost of an automobile seat, a wing screw threaded through the tubular member and the corner post Ybeing provided with an aperture through which the ,wing screw may extend,vthe tubular member being provided with a slot opposite the wing screw, a seat back frame having an end extending adjacent theA said slot, a pivot pin carried by the said end and ridingv in the slot, thepivot pin being provided with a recess in the head to receive the wing screw, `a stop on the corner -post for` supporting the seat vback rframel in the upright position, the said seat backrframe pivot pin is raised to the top of its slot and a stop on the tubular member adapted to supportthe vseat backv in substantially horizontal position when turned past the stop o n thecorner post.

3. In a hinge for automobile seats/including a pair or vcorner posts and a'pivoted seat back frame, a tubular member'adapted--to be secured over each corner post,"a wing' screw carried by the tubular member, andthe tubular member being provided withra slot opposite the wing screw, a pivotpin carried by the seat back frame and slidably mounted in the slot, the pivot pin being provided with afrecess to receive the end of Lthe wing screw each corner post being provided with a shoulder and the seat backframe being adapted to engage the shoulder in normal use. f f v PAUL v.
